# Changes
## Unreleased - 2021-xx-xx
* Remove `trust-dns-proto` and `trust-dns-resolver` [#248]
* Use `tokio::net::lookup_host` as simple and basic default resolver [#248]
* Remove `trust-dns-proto` and `trust-dns-resolver`. [#248]
* Use `std::net::ToSocketAddrs` as simple and basic default resolver. [#248]
* Add `Resolve` trait for custom dns resolver. [#248]
* Add `Resolver::new_custom` function to construct custom resolvers. [#248]
* Export `webpki_roots::TLS_SERVER_ROOTS` in `actix_tls::connect` mod and remove
the export from `actix_tls::accept` [#248]
* Remove `ConnectTakeAddrsIter`. `Connect::take_addrs` would return
`ConnectAddrsIter<'static>` as owned iterator. [#248]
* Remove `ConnectTakeAddrsIter`. `Connect::take_addrs` now returns `ConnectAddrsIter<'static>`
as owned iterator. [#248]
* Rename `Address::{host => hostname}` to more accurately describe which URL segment is returned.
[#248]: https://github.com/actix/actix-net/pull/248
